YUKON, Okla. – Don Parrish said he’s been feeling a whole lot of shaking at his home near S.W. 29th and Czech Hall Road.

“When it hit the house, it was loud. I mean, and it shook,” Parrish said. “It’s beginning to be quite a few earthquakes around. We used to didn’t have a thing.”

“The earthquake activity around Yukon has come on very hard and very fast. And, so, over the holiday, we have been working it,” said Matt Skinner with the Oklahoma Corporation Commission.

The OCC has been investigating and said the recent earthquakes have been linked to a fracking well at S.W. 44th and Richland Road.

“We’ve been working with that operator since Thursday to modify their frack stages to mitigate the risk of felt earthquakes,” Skinner said.

According to the Oklahoma Geological Survey, there have been two earthquakes near Yukon and 6 near the southwest corner of Canadian County in the last 15 days.

But, all of the shaking also comes on the heels of seismic testing in the area.

An out-of-state company just finished the testing that’s been going on since the beginning of October.

It involved vibrator trucks that actually shake the ground to determine if there’s any oil underneath.

“They vibrate the ground, and it’s a pretty good roar when they do that,” Parrish said.

But, both the Corporation Commission and Oklahoma Geological Survey said there is no credible evidence seismic testing can cause earthquakes.

“They all say that there’s no link to seismic activity and that kind of seismic testing,” Skinner said.

The more likely cause is the hydraulic fracturing.

After a 2.7 earthquake around 2:30 Monday morning, the volume at the S.W. 44th and Richland Road well was reduced once again in the hopes of stopping the quakes.

The well is owned by Citizen Energy.

The company told the Corporation Commission hydraulic fracturing operation should end by December 5.
